Continous Flow with rockwool?

Ok, so I'm about to start a drip system with net pots filled with hydroton rocks and a rockwool cube in the center of each for my seeds.

My question is, will i be able to leave my drip system on, or should I use a watering schedule because of the rockwool?

I don't know anyone who leaves the drip system on 24/7. They have all used timers. Read the GrowFAQ here for more info, and click on the link to another site which may help explain the systems to you.
